Instead of letting AUTOLOAD receive and pass on arguments, and instead
of letting AUTOLOAD call the loaded sub, why not have AUTOLOAD do its
thing, and then have *perl* call the sub?
sub AUTOLOAD ($whatever) { # but no [EMAIL PROTECTED]
my $s = get_subref_for $whatever;
our &::($whatever) := $s;
return $s; # non-subref indicates failure
}
You are of course assuming that every use of AUTOLOAD, for all time,
will result in
a) Calling another function
b) An error
Wouldn't this lead to hacks where people do things like this just to
prevent perl thinking it's a failure?
sub AUTOLOAD ($whatever) { # but no [EMAIL PROTECTED]
my $s = get_subref_for $whatever;
our &::($whatever) := $s;
return sub () { 1 };
}
The ability to get complete control over the params and context of the
function, and maybe run something else AFTER the function call is important.
So I suspect there might be some false economy in this optimisation.
